REVERSIBLE PLOW.

SPECIFICATION forming part of Letters Patent No. 312,438, dated February17, 1885.

Application filed June 5, 1584. (No model.)

To aZZ whom, it may concern:

Be it known that I, JESSE L. DELANO, of Northampton, in the county ofHampshire and State of Massachusetts, have invented a new and usefulImprovement in Reversible Plows, of which the following is a full,clear,

and exact description.

My improvements relate to plows having revolving mold-boards, the object, being to obtain a construction that allows reversing of themold-board with greater ease than with plows as heretofore made, andthat can be manufactured with greater facility.

The essential features of the invention consist in the point madeseparately from the mold-board and hung to swing on a horizontalaxis,and a double-sided mold-board swing ing on'a vertical axis, ashereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a plan view of the improved plow. Fig. 2 is a side elevationwith the moldboard partly broken away. Fig. 3 is a crosssection on lineit x of Fig. 2, and Fig. 4 is a front view of the plow as arranged toturn a furrow both ways.

The beam a is provided with a rear standard, b, that gives support tothe gearing that operates the movable mold-board and point.

The mold board A is formed double, or alike on either side, and at theangle of its forward end is hung by pivots c to a vertical post, d,depending from the beam a. The point B is shaped at its rear end tocoincide with one half the end of board A, and is attached rigidly to ahorizontal bar, j, which is hung in eyes 6 e at the lower ends ofstandard I) and post cl, so that it passes beneath the moldboard. To barfis swiveled an arm, g, extending up into the hollow center of themold-- board and entering a tubular rod, ii, that is swiveled to afixture on the board A, so that when the mold-board is swung to right orleft the barf and point B are rocked.

For shifting the board and point right and left, I provide a verticalshaft, 1', which is sustained by beam a and standard I), and has ahorizontal arm, 70, with an eye at its outer end, engaging aslide-rod,I, attached upon the mold-board. The shaft i has handles for itsconvenient operation to swing the mold-board to its right or leftposition and turn the point over upon its axis. Only a slight movementof the shaftt' is required to shift the plow, and the parts work easily.The point is pro vided with spring-catches m m, that take behind thepost (i and beneath the edge of the mold'board so as to lock the partstogether.

Any suitable means may be employed to shift the plow. I do not limitmyselfin that respect, nor to a moldboard of any special shape, as it isevident the shape may be varied. The advantages of this constructionare, that the parts ofthe plow can be readily manufactured, and are notexpensive, and the operation of shifting being easy removes agreatobjection to this class of plows as heretofore made.

By placing and securing the parts in a mid way position, as shown inFig. 4, the plow will turn a furrow both ways.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a reversible plow, the point B, with its lower edge in line withits apex, pivoted to swing upon a horizontal axis, in combination withthe mold-board A, of an approximately A shape, pivoted centrally of itslength to swing horizontally upon a vertical axis, whereby the point andboard are adapted to turn the earth either to the right or the left, orto turn it both ways, substantially as described.

2. The combination. in a plow, of hinged mold-board A, post d, hingedpoint B, and horizontal bar f, said point being fixed to said bar at itsapex, and said bar being connected to the mold-board by a swiveledtelescopic connection. together with means to shift the mold-board,substantially as shown and described.

3. The combination ofpoint B, mold-board
